LOL!!!!!!!!!!!!!!!!Physicians know nothing about
basic physics. They are the last ones to listen to about
what a mask does or does not do. They simply repeat information, and its incorrect info on this subject.
Ive worked in physics , airflow and filtration labs testing and designing various applications/materials/scenarios from large to small particles, with patents in these areas as well ...and physics does not lie. As long as your on Earth the principle stays the same. I'd think most adults would be able to understand this at the basic level. A mask at its simplest form is a filter, not much different then your coffee or furnace filter in what it does. Even if things go through a filter the trajectory and velocity is changed from its natural pattern, which, with covid, is a good thing.
The effectiveness of out going particle capture and velocity and distance obviously depends the the mask type, material, and fit. The duck dynasty and or "hipster" beard will affect the mask seal a lot, thus it will leak.
So if you are in proximity to others this will help slow the spread / shorten distance of your breath ("or cough cloud") and particles/droplets ect to others nearby.
And caring about
others should matter. Or do we not care anymore?
The other possible fact that covid might transmit via our eyes is an added cautionary, it does NOT cancel out the affect of a mask. Where done covid come from? > obviously your mouth and nasal passages.
The fact that some are STILL arguing about
masks is ridiculous.
